/**
 * <p>Simple {@link TimerTask} implementation that sends a message to a channel. It shows how easy it is
 * to send Bayeux messages through a {@link BayeuxChannel} object.</p>
 *
 * <p>The Spring configuration for this bean is as follows:</p>
 * 
 * <pre>
 * &lt;bean id="broadcastChannel" class="com.polarrose.spring.bayeux.impl.BayeuxChannelImpl">
 *   &lt;property name="name" value="/broadcast"/>
 * &lt;/bean>
 *
 * &lt;bean id="broadcastTask" class="com.polarrose.spring.bayeux.examples.broadcast.BroadcastTask">
 *   &lt;property name="channel" ref="broadcastChannel"/>
 * &lt;/bean>
 * </pre>
 *
 * <p>Note that this example does not use a {@link com.polarrose.spring.bayeux.BayeuxClient} and thus
 * the message has an anonymous sender.</p>
